The objective of this study was to evaluate the 5-year radiographic bone loss surrounding implants treated with surface airborne-particle abrasion and acid etching (SA). This retrospective study was conducted at a private clinic in Los Angeles, California, USA, and included 100 patients with a total of 188 implants with an SA surface treatment. Five years after implantation, the patients were radiographically evaluated for bone loss adjacent to the implants. Each radiograph was digitized and uploaded to an online measuring instrument. Bone loss was determined by subtracting the measurements at the 5-year follow-up from the initial measurements acquired from radiographs taken at the time of implant placement. The posterior mandible, posterior maxilla, anterior mandible, and anterior maxilla received 90, 74, 6, and 18 implants, respectively. The average marginal bone vertical remodeling values on the mesial and distal surfaces of the implants were 1.19 mm and 1.25 mm, respectively, which were significantly lower than the 2.3-mm loss previously reported for other implants. Marginal bone remodeling was visible on radiographs; however, the bone levels surrounding the implants remained essentially stable after 5 years of function.
This split-mouth trial investigated the efficacy of treating bilateral gingival recessions with either a xenogeneic cross-linked collagen matrix (CCM) or recombinant human platelet-derived growth factor-BB (rhPDGF-BB) with a bone allograft (AG). Ten patients were treated with a coronally advanced flap, either with CCM or rhPDGF-BB + AG. The primary outcome was percentage of mean root coverage (mRC) at 12 months. Additional outcomes included clinical and volumetric measurements; patient-reported outcome measures (PROMs) for pain, swelling, and esthetics; and ultrasonographic assessment of gingival thickness (GT) and position of the buccal bone. At 12 months, both groups showed significant improvements, with an mRC of 78.6% in the CCM group and 82.3% in the rhPDGF-BB + AG group. A 3D analysis of both groups showed comparable volumetric gain. CCM-treated sites displayed higher ultrasonographic echogenicity in GT (P < .01) than rhPDGF-BB + AG sites. The rhPDGF-BB + AG group showed greater reductions in the buccal bone dehiscence (mean: 2.03 mm; P < .01), less swelling during the first 3 days, and slightly greater mRC. CCM and rhPDGF-BB + AG were effective in treating multiple adjacent gingival recessions. CCM promotes greater gains in gingival thickness, while rhPDGF-BB + AG resulted in significantly less buccal bone dehiscenace.
Digital dentistry has accelerated the precision and predictability of full-arch implant therapy, particularly through the use of stackable guide systems that coordinate bone reduction, implant placement, and prosthetic positioning. Immediate loading has simultaneously become a widely adopted strategy for edentulous rehabilitation. This case report describes a fully guided dual-arch reconstruction incorporating guided bone reduction, guided implant placement, and guided provisional prosthesis delivery using a four-part stackable guide system with novel 3D-printed direct-to-multiunit abutment (MUA) temporary cylinders. This approach increases material bulk around screw-access channels, eliminates on-site conversion procedures, and enables direct-to-MUA prosthesis delivery without same-day printing.
This study analyzed articles published in The International Journal of Periodontics & Restorative Dentistry (IJPRD) through a bibliometric and altmetric review. In August 2025, a search was conducted in Scopus. Bibliometric data were extracted from all included studies. VOSviewer was employed to generate collaboration maps. Altmetric data were retrieved from Dimensions. A total of 3,001 articles were included. Articles were published between 1981 and 2025. There was a prevalence of research articles (n = 2,438), primarily case reports and series (n = 947). The United States stood out (n = 1,212) as a primary nation of origin for articles published, with the University of Michigan (n = 217) predominating. M. Nevins (n = 153) was the most productive author. Mendeley readers and X social media platform showed substantial interest in the publications. There has been a predominance of research articles over the years, particularly case reports, originating from the United States. Future submissions of systematic reviews are encouraged. Submissions from African and Oceanian countries are also encouraged.
Periodontitis stage IV may be characterized by pathologic tooth migration (PTM), which, when orthodontic correction is needed, represents the conditions that define the type 2 phenotype, according to the European Federation of Periodontology Clinical Practice Guidelines. Here, four clinical cases of patients with stage IV, type 2 periodontitis and deep intrabony defects adjacent to the migrated teeth are presented. After successfully completing steps 1 and 2 of periodontal treatment, the intrabony defects were subjected to regenerative periodontal surgery, and active orthodontic movement began soon (2 to 4 weeks) after surgery. Follow-ups of up to 24 months demonstrate the effectiveness of interdisciplinary periodontal-orthodontic treatment in controlling inflammation, regenerating intrabony defects, and realigning pathologically migrated teeth, thereby restoring esthetics and function for the patient.
